About Dublin
Dublin is a proper pub city — Temple Bar is for tourists, but head to Stoneybatter or Smithfield for where locals actually drink. Trinity College is gorgeous, the Guinness Storehouse is overrated but you'll probably go anyway, and Irish hospitality is real. Day trips to Cliffs of Moher or Glendalough are easy and worth it.

- •Trinity College Long Room library
- •St. Stephen's Green for a park break
- •Day trip to Cliffs of Moher (3 hours west)
